In vector, magnitude represents the size of the quantity, which is also its absolute value, while direction represents the side, i.e. east, west, north, south, etc. We express vector quantities in either of the parameters i.e. one-dimensional, two-dimensional, or three-dimensional parameters...

Physical Meaning- Both scalar and vector quantities describe physical properties or measurements of objects or phenomena in the physical world. Scalars describe quantities like distance, speed, temperature, energy, etc., while vectors describe quantities like displacement, velocity, force, acceleration, et...
Scalar quantitieshave a size or magnitude only and need no other information to specify them. Thus, 10 cm, 50 sec, 7 litres and 3 kg are all examples of scalar quantities. Vector quantities have both a size or magnitude and a direction, called the line of action of the quantity. Why i...

Thus, 10 cm, 50 s, 7 l, and 3 kg are all examples of scalar quantities. Vector quantities have both a size or magnitude and a direction, called the line of action of the quantity. Thus, a velocity of 50 km/h due east, on acceleration of 9.8 m/s 2 vertically downward, and a ...
Describe what is meant by scalar and vector quantities, giving examples, Distance as an example of a scalar quantity and displacement as an example of a vector quantity, Describe how a vector quantity can be represented by an arrow, examples and step b
How to Distinguish Between Vector and Scalar Quantities Step 1:Identify the units for the quantity and determine if the quantity described has a direction associated with it. Step 2:Identify the quantity as a vector or a scalar. Vector quantities involve a magnitude (number) with units and a ...
